Co-Patriarch candidacy in 2010 Bishop Sebouh Chouldjian was one of the three candidates for the Co-Patriarch at the
Armenian Patriarchate of Constantinople in 2010.
Mesrop II Mutafyan, the Armenian Patriarch of Constantinople was diagnosed with
Alzheimer's disease in July 2008, and was incapable of running the Patriarchate since then. This led the Armenian community to a painful condition of uncertainty. In late 2009, the Patriarchate's Religious Council wrote to the Turkish government seeking permission to elect a coadjutor (co-Patriarch). Three bishops stated that they were going to run for the elections: Bishop Sebouh Chouldjian, Archbishop Karekin Bekchian – the Primate of the Armenian Church Diocese of Germany, and Archbishop Aram Ateshian – the chairman of the Supreme Spiritual Council of the Patriarchate of Istanbul. He paid particular attention to the importance of dialogue among Armenians and between Turkish and Armenian people. On 10–17 February 2010 Bishop Sebouh visited
Istanbul, Turkey to have meetings with the Armenian community of Istanbul. During his meetings and interviews he urged to continue
Hrant Dink's way (i.e. dialogue between Armenian and Turkish people) and keep Armenian Patriarchate free from politics. On 29 June 2010 the
government of Turkey made a decision to reject the request of the Armenian community of Turkey to allow co-patriarch elections. The Turkish Government said that they did not find the elections of either patriarch or co-patriarch reasonable and allowed carrying out only the elections of Patriarchal
Locum Tenens. Hours later Archbishop Shahan Svajian – the that time Locum Tenens, resigned and the Spiritual council of the Patriarchate elected Archbishop Aram Ateshian a new Patriarchal Locum Tenens. which was disallowed by the Turkish government after unsuccessful negotiations of Armenia-Turkey reconciliation. Later, in his letter to the Armenian Community of Turkey from 15 July 2010 Bishop Sebouh mentioned that interference of Turkey's Government was in contradiction with the adopted new policy on dealing with ethnic minorities. "We continue to hope that this is not the manner of actions of
Erdoğan's government, but that of the stationary state sub-agencies, which hamper the democratic development of Turkey with their old mentality". Bishop Sebouh said it was the moral obligation of Archbishop Aram Ateshian to send a new letter to the Turkey's Government with request to hold the elections of Co-Patriarch. though it was hardly possible to hold new patriarch elections as long as the current patriarch Mesrop II was alive. The "We Want to Elect Our Own Patriarch Initiative" remained active and held silent protests in Armenian churches on Sundays. Archbishop Sebouh occasionally visited Turkey and expressed his position and opinion on issues warring the community.
Patriarch candidacy in 2016 2016 gave rise to a new wave of demands to eventually elect the head of the Armenian Church in Turkey. In spring 2016 two of the four main candidates, Archbishop Sebouh and Archbishop Karekin Bekdjian urged that there be patriarch election "now". Archbishop Sebouh declared that should there be election of patriarch there was no obstacle for him to be a candidate. "If the society finds me qualified for solving the problems of Armenian society and the patriarchate, I am ready to serve by considering it as a holy duty," he said. In June 2016 a group of Turkish Armenians protested in front of the Armenian Patriarchate against being denied the right to replace acting Locum Tenens Aram Ateşyan whose reputation was compromised after his letter to president
Recep Tayyip Erdoğan, wherein he criticized a recent decision by the German Bundestag recognizing the World War I-era killings of Anatolian Armenians. In October 2016 the Clerical Assembly of the Armenian Patriarchate of Turkey decided to superannuate the Patriarch Mesrob II on the grounds that he has been unable to perform his duty for 7 years and announced that there will be an application for starting the election process.
Patriarch candidacy in 2019 On 8 March 2019 Patriarch Mutafian died at the age of 62. This event provoked new discussions about the patriarch elections. Back then experts predicted that the two main candidates for the patriarch would be Archbishops Sebouh Chouldjian and Aram Ateshian. On 27 September 2019 Archbishop Sebouh Chouldjian released a statement requiring from the Turkish government to restore the original text of the 25th clause of canonical regulation which was violating the rights of bishops from outside Turkey. In October 2019, following Archbishop Garegin Bekchyan, Archbishop Sebouh called on Archbishops Sahak Mashalyan and Aram Ateshian to rise above personal ambitions and consider the long-term interest of the Armenian community and stand in favor of supporting the rights of bishops outside Turkey. On 5 December 2019 Archbishop Sebouh released an official statement regarding the election of 85th Armenian Patriarch of Constantinople, indicating that he "forgives everyone", who caused his disentitlement. He said: "It is now beyond any doubt, that the reason for the staging of the "canonical change" was myself, since the support for me by a significant portion of faithful Armenian people in Turkey could be decisive". He condemned this as an outrageous historical injustice and indirectly pointed out the nefarious role of Archbishops Sahak Mashalyan and Aram Ateshian. On 11 December 2019 Bishop Mashalian was announced the 85th Armenian Patriarchate of Constantinople. ==Honors and awards==
